This is a little worrying for me.
The way to protect my DD, with weak AA, from a CV attack was smoke but also maneuvering so the planes didn't come in my defection circle. So long they don't spot you. They don't know you are there.
But with this they always know where the closest ship is. It isn't like you can outrun planes in a DD.
I don't think this is a good idea. It makes it TOO easy for a CV.

Things that have changed for the second round of the test.
Changed the settings of AA fire and "Defensive AA Fire" equipment. Now the effectiveness of this equipment is higher, but the reload time is lower. This will help to build a stronger defense against aircraft raids.
Changed the settings of explosions of shells from long and medium range AA guns. Now they deal more damage and are more effective against the enemies’ aircraft.
Torpedo bombers were added and the settings of attack aircraft changed on IV tier carriers. This adjustment will make the low-tier gameplay more interesting and will provide more options forplayers.
Changed the setting of aiming for Japanese bombers. Now you can reach almost maximum aim during the preparation for attack, and drop the bomb with higher accuracy. This change will allow players to attack battleships more effectively by dropping the bombs at a right angle to the deck.
Fixed the display of torpedo drop zone with the “Torpedo Acceleration” skill equipped.
Fixed an issue that caused catapult planes' models to not be displayed on the ship and appear only after the equipment was first used
Fixed an issue that caused catapult planes' model to remain on the ship after takeoff or depletion of the equipment
Fixed an issue in the autopilot settings, due to which the ship began to move in reverse
Fixed an issue due to which when you rotate camera and observe could get inside the model aircraft squadron
Optimized number of air defense effects for more comfortable squadron play
Fixed an issue due to which patrol fighters attacked squadrons even under the condition that they had time to get out of the attack zone of patrol fighters

It's still missing the pvp part between CL/CA/DD/BB and enemy CV. Doing 1 step less than the proposed AA workings would literally be doing nothing.
It would have been a great opportunity to come up with a better system.
To be clear the current AA system was bad and very minimal. I also didn't liked it. Clicking 1 squadron was very minimal.

I don't need to do the math. I'm not the 1 whining about it. I don't care if I didn't got some flags/boxes/... So far that I can remember most of such WOWs events always had such mechanisme of buy the premium-ship-and-do -the-mission-quicker (or something in that trend). But the system says you can do the day-directive with those RN DD. And if you complet a directive you get 1 Guinea. The game doesn't demand you to do all missions to be successful.I just doing the event how it's designed.
For me the big price is at the end and it's that premium Cossack. So yes that 1 Guinea is for me the most important aspect of this event. The rest is in the long run only easy silver to me.
I wouldn't be surprised that everybody that do all the directives will get the 4 ships by the end of the second month.
But people want to get all ships in the first day of the first week in the first month of a 3 months event;. And than they get 180 boxes.

24% is an exaggeration so far i can tell. At least it didn't seem to me. Secondly to get that 1 guinea you didn't need a RN DD. Also you could get a premium RN DD some flags/boxes are so important to you.
Like I said this event will end just before Christmas. And people want all their gifts in the last week of september.
